Given below are two statements : Statement I: In a vernier callipers, one vernier scale division is always smaller than one main scale division. Statement II: The vernier constant is given by one main scale division multiplied by the number of vernier scale divisions. In the light of the above statements, choose the correct answer from the options given below. [JEE Main 2025, 22 Jan (Shift 1)]
aStatement I is false but Statement II is true
bStatement I is true but Statement II is false
cBoth Statement I and Statement II are false
dBoth Statement I and Statement II are true
✓ Correct answer: b) Statement I is true but Statement II is false
Explanation(2) A vernier scale is designed such that its divisions are slightly smaller than the main scale divisions.This difference allows precise measurements by aligning a particular vernier division with the main scale.The vernier constant (least count) is actually given by: Least Count = Value of One Main Scale Division-Value of One Vernier Scale Division Thus, the correct option is: 2
